POLYPIPE Terrain’s Acoustic dB12
piping system has been implemented in
the new Saxton residential development
in Leeds, UK. The dB12 pipes and
fittings have been used to create soil
and waste systems that provide a
high degree of acoustic insulation and
prevent noise transmission within the
new Urban Splash development. The
development involves the complete
refurbishment of two tower blocks that
previously provided accommodation for
housing authority tenants.
The prevention of noise transmission
between the new apartments demanded
an acoustically insulated piping system
that would provide reliable and effective
performance.
Terrain Acoustic dB12 was specified
by mechanical engineers RAD
Mechanical Services Ltd. “We have
used Terrain’s PVC above-ground
soil and waste system on a large
number of developments in the past
and it has always provided excellent
performance,” commented RAD’s Mark
Radcliffe. “We were naturally keen to
see if the Acoustic dB12 system which
was launched recently could meet our
specifications and perform to the same
high standards, which it has. Polypipe
Terrain worked with us to overcome
some initial technical issues, and once
work started we found the Acoustic
dB12 system to be both quick and easy
to install.”
The pipes and fittings in the Terrain
Acoustic dB12 range allow the creation
of soil and waste piping systems in multi-
occupancy buildings such as hotels,
apartments, hospitals and schools,
where minimal noise transmission is
a key requirement. The three-layer
construction allows the pipes and fittings
to provide acoustic performance that
surpasses the requirements of Building
Regulations Part E, and to also meet
Class B1 fire protection standards.
A wide variety of components, pipes
and fittings are available, providing
flexibility in system design and allowing
an acoustically insulated drainage
system to be created for virtually any
application.
